The SPASE Data Model: A Metadata Standard for Registering, Finding, Accessing, and Using Heliophysics Data Obtained From Observations and Modeling

Abstract

The Space Physics Archive Search and Extract Consortium has developed and implemented the SPASE Data Model that provides a common language for registering a wide range of Heliophysics data and other products. The Data Model enables discovery and access tools such that any researcher can obtain data easily, thereby facilitating research, including on space weather. The Data Model includes descriptions of Simulation Models and Numerical Output, pioneered by the Integrated Medium for Planetary Exploration (IMPEx) group in Europe, and subsequently adopted by the Community Coordinated Modeling Center (CCMC). The SPASE group intends to register all relevant Heliophysics data resources, including space‐, ground‐, and model‐based. Substantial progress has been made, especially for space‐based observational data and associated observatories, instruments, and display data. Legacy product registrations and access go back more than 50 years. Real‐time data will be included. The National Aeronautics and Space Administration (NASA) portion of the SPASE group has funding that assures continuity in the upkeep of the Data Model and aids with adding new products. Tools are being developed for making and editing data descriptions. Digital Object Identifiers (DOIs) for Data Products can now be included in the descriptions. The data access that SPASE facilitates is becoming more uniform, and work is progressing on Web Service access via a standard Application Programming Interface. The SPASE Data Model is stable; changes over the past 9 years were additions of terms and capabilities that are backward compatible. This paper provides a summary of the history, structure, use, and future of the SPASE Data Model.

Solar Terrestrial Relations Observatory (STEREO) Observations of Stream Interaction Regions in 2007 – 2016: Relationship with Heliospheric Current Sheets, Solar Cycle Variations, and Dual Observations

“…In total, STA and STB observed 575 SIRs in 2007 -2016, and the survey is provided to the public as a Level 3 product from the STEREO mission with multiple file formats at wwwssc.igpp.ucla.edu/forms/stereo/stereo_level_3.html, including one for the Space Physics Archive Search and Extract (SPASE: Roberts et al, 2018), which is the uniform metadata for the Heliophysics Data Environment (hpde.gsfc.nasa.gov/index.html). About 50 (8.7%) of SIRs, although still meeting SIR criteria, are hybrid events combined with ICMEs, marked by an asterisk in the survey.…”

Cross-comparison of global simulation models applied to Mercury’s dayside magnetosphere

“…In the present study, we employ Paraview for 3D data visualization and analysis. In addition, we use 3Dview and AMDA, which makes use of the SPASE simulation data model [44,45,46,47]. Using SPICE kernels, 3Dview is a 3D JAVA tool that…”
